Dominant Aerobic Bacterial Community of Sea Bass (Dicentrarchus Labrax L.1758) Larvae During Weaning from Artemia to Dry Feed in Culture Conditions
The aim of this study was to determine the dominant aerobic bacterial community of sea bass larvae during their weaning period in 2 different marine hatcheries in Muğla-Bodrum region. Samplings were made in January, March, and May 2005. Larvae and water samples were diluted in certain ratios and were inoculated to Marine Agar, TCBS Agar, Pseudomonas Agar, King Bee Agar, MRS agar, Blood Agar and Plate Count Agar, in that order. Water temperature, pH, saturation, salinity, and features of the system used were recorded. Isolated bacterial strains were identified with standard biochemical methods and API 20E Rapid Identification Kits. In this study the total number of bacterial strains was detected as 109 and the number of all bacteria species was found as 18. At the end of this study Vibrio species were identified as the dominant species of the bacterial flora of sea bass larvae.
